After I accelerate to about 50 mph, it starts after a few minutes at that speed. When I touch the brake it stops but starts again. It goes on for about 15 minutes and then all of a sudden it will stop (sometimes it never stops). Once I get off the highway and resume normal speed, it never happens. It does the "highway" whistle every time.
